Operational problemsFirst read and observe the introductory information and safety warn-
ings
on page 91.
If the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be.
› One of the fuses has blown. Check the fuse and replace if necessa-
ry » page 236 .
› The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot » page 11.
If you are not able to resolve the operational problem yourself, or if the cooler output has reduced, switch off the cooling system and seek assistance from a
specialist garage.
Auxiliary heating (auxiliary heating and ventilation)
Introduction
This chapter contains information on the following subjects:
Switching on and off directly

Conditions for the functioning of auxiliary heating (Aux. heating and ventilation),
hereinafter referred to only as auxiliary heating (Aux. heating).
The charge state of the vehicle battery is sufficient.
The fuel supply is adequate (the warning icon
is not lit in the display of the
instrument cluster).
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by
switching off the engine, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) can be used when stationary, when the engine is switched off to preheat the vehicle and also while driving (e.g. during
the heating phase of the engine).
The auxiliary heater (parking heater) functions in connection with the air-condi-
tioning system or Climatronic.
The auxiliary heating (auxiliary heating) also warms up the engine.
The auxiliary heating (parking heating) warms up the coolant by combusting fuel
from the vehicle tank.
The coolant warms up the air, which (if the blower speed is not set to zero) flows into the passenger compartment.WARNING■ The auxiliary heater (independent vehicle heater) must never be operated in
closed rooms (e.g. garages) – risk of poisoning!■
The auxiliary heating (parking heating) must not be allowed to run during re-
fuelling – risk of fire.
■
The exhaust pipe of the auxiliary heating is located underneath the vehicle.
Therefore, if you wish to operate the auxiliary heating (auxiliary heating), do
not park the vehicle in such a way that the exhaust gases can come into con-
tact with highly flammable materials (e.g. dry grass) or easily inflammable sub-
stances (e.g. spilt fuel) – risk of fire.
CAUTION
■ The running auxiliary heating (auxiliary heating) consumes fuel from the vehicle
tank and automatically controls the filling level. If only a low quantity of fuel is
present in the fuel tank, the auxiliary heater switches itself off.■
The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
■
If the auxiliary heating is running, the vehicle battery discharges. If the auxiliary
heating and ventilation has been operated several times over a longer period, the
vehicle must be driven a few kilometres in order to recharge the vehicle battery.
Note
■ The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating problem.
97Heating and air-conditioning
■The air inlet in front of the windscreen must be free (e.g. of ice, snow or leaves)
to ensure that the auxiliary heating (aux. heating) operates properly.■
So that warm air can flow into the vehicle interior after switching on the auxili-
ary heating, you must maintain the comfort temperature normally selected by you, leave the fan switched on and leave the air outlet vents in an open position.It is recommended putting the air flow in the position or .

Button for switching on/off the system directly on the operating
part of the air conditioning/Climatronic
First read and observe the introductory information and safety warn-
ings
on page 97.
The auxiliary heating (auxiliary heating and ventilation) can be directly switched
on or off at any time using the button » page 99 » Fig. 96 on the operating part
of the air-conditioning system
, on the operating part of the Climatronic system
or via the radio remote control.
If the auxiliary heating and ventilation has not already been switched off, it switches off automatically after the running time set in the Running time menu.
After switching off the auxiliary heating, the coolant pump runs for a short period.
System settings
First read and observe the introductory information and safety warn-
ings
on page 97.
The following menu items can be selected from the Aux. heating menu item in
the MAXI DOT display (depending on the vehicle equipment): ■ Day of the wk. - set the current day of the week
■ Running time - Set the required running time in 5 minute increments. The run-
ning time can be 10 to 60 minutes.
■ Mode - Set the desired heating/ventilation mode
■ Starting time 1 , Starting time 2 , Starting time 3 - for each pre-set time, the day
and the time (hour and minute) can be set for switching on the auxiliary heating
and ventilation. An empty position can be found between Sunday and Monday when selecting the day. If this empty position is selected, the activation is per-formed without taking into account the day.
■ Activate - Activate pre-set mode
■ Deactivate - Deactivate pre-set mode
■ Factory settings - Restore factory settings
■ Back - Return to main menu
Only one programmed pre-set time can be active.
The last programmed pre-set time remains active. After the auxiliary heating activates at the set time, it is necessary to pre-set a
time again.
If the pre-set menu is closed by selecting the Back menu item or if no changes
are made on the display for more than 10 seconds, the set values are stored, but
the pre-set time is not activated.
An indicator light on the button
is illuminated when the system is running.
The running system deactivates after expiration of the operating period or can be
deactivated earlier by pressing the button to directly switch on/off the auxiliary
heating

First read and observe the introductory information given on page 125.
Always depress the clutch pedal all the way down. This prevents uneven wear on the clutch.
The gear recommendation must be observed when changing gear » page 24.
Only engage reverse gear when the vehicle is stationary. Depress the clutch pedal
and hold it fully depressed. Wait a moment before reverse gear is engaged to
avoid any shift noises.
The reversing lights will come on once reverse gear is engaged, provided the igni- tion is on.
125Starting-off and Driving

When accelerating, the gearbox automatically shifts up into the higher gear just
before the maximum permissible engine speed is reached.
If a lower gear is selected, the gearbox does not shift down until there is no riskof the engine overrevving.
Note
It may be beneficial, for example, when travelling downhill, to use manual shifting
of gears. Shifting to a lower gear reduces the load on the brakes and hence the
wear of the brakes » page 124.

Kickdown
The kickdown function allows you to achieve the maximum acceleration of your
vehicle while driving.
When the accelerator pedal is fully depressed, the kickdown function is activated
in any forward driving mode.
The gearbox shifts down one or more gears depending on the vehicle speed and engine speed, and the vehicle accelerates.
The gearbox does not shift up into the highest gear until the engine has reached
its maximum revolutions for this gear range.
WARNINGRapid acceleration, particularly on slippery roads, can lead to loss of control of
the vehicle – risk of accident!
Malfunction
First read and observe the introductory information and safety warn-
ings

Emergency programme
The transmission switches to the emergency programme, if there is a fault in the automatic gearbox system.
Indications of an activated emergency programme include the following.
› Only certain gears are selected.
› The reverse gear
R cannot be used.
› Shifting gears in Tiptronic mode is not possible.
Gearbox overheating
The gearbox may become too hot due to frequent repeated starting or stop-and-
go traffic, for example. Overheating is indicated by the warning light » page 14,
Clutches of the automatic gearbox are too hot .
128Driving
The automatic start procedure takes place again. The warning symbol goes
out.
Further information on automatic transmission Engine shut down takes place when the selector lever is in positions P, D , S and N
and in Tiptronic mode.
When the selector lever is in position P the engine remains shut down after you
release the brake pedal. Start the engine by pressing the gas pedal or by moving
the selector lever into a different mode and releasing the brake pedal.
If the selector lever is moved into position R during the STOP phase , the engine
will re-start.
No automatic engine shutdown takes place when the vehicle is moving at low
speed (e.g. during a traffic jam or when tuning) and remains stationary after pressing the brake pedal lightly. Automatic engine shutdown takes place if you
press the brake pedal down with more force.
Operating conditions of the system
First read and observe the introductory information and safety warn-ings
on page 149.
The START-STOP system is very complex. Some of the procedures are hard to check without servicing.
No engine shut down is carried out
Before each STOP phase, the system checks whether certain conditions have
been met. No engine shut down takes place in the following situations.
› The engine has not reached the minimum temperature for START STOP mode.
› The temperature inside the vehicle has not reached the desired temperature
set in the air-conditioning system/heating.
› The external temperature is very low/high.
› The intensive windscreen heater (Climatronic) or windscreen heater/ventilation
is switched on with the maximum air temperature setting (manual air condition-
ing system).
› The parking aid/Park Assist is switched on.
› The charge state of the vehicle battery is too low.
› The stationary vehicle is on a steep slope or a steep downhill section.
› The idling speed is too high.
› The steering angle is too large (manoeuvring).
› The selector lever position
R is selected (e.g. when parking).
The warning symbol appears in the instrument cluster display.
The automatic start procedure takes place again
During the STOP phase, the engine fires up without any active driver intervention, e.g. in the following situations.
› The vehicle begins to roll, e.g. on a slope.
› The difference between the temperature setting of the air-conditioning sys-
tem/heating and the temperature of the interior is too large.
› The intensive windscreen heater (Climatronic) or windscreen heater/ventilation
is switched on with the maximum air temperature setting (manual air condition-
